TraceSpan’s VDSL Xpert(TM) Analyzer Supports G.INP

RA'ANANA, Israel, July 20, 2011 /PRNewswire/ --

TraceSpan Communications, a leader in broadband analysis and monitoring
solutions, announced today the release of G.INP support for its VDSL
Xpert(TM) analyzer. This follows a similar announcement for the company's
DSL Xpert(TM) analyzer in December of last year and completes G.INP support
in all of the relevant TraceSpan analyzers.

G.INP, which has recently been standardized by ITU in the G.998.4
recommendation, is intended to provide enhanced protection against impulse
noise or increase the efficiency of providing impulse noise protection
(INP). This is accomplished with new techniques applying physical-layer
retransmission.

VDSL Xpert(TM) is a multi-layer analyzer, which provides a complete and
accurate analysis of VDSL2 product performance and interoperability with no
affect of the data transfer between the transceivers. Now, with its new
G.INP capability, VDSL Xpert(TM) allows its users to verify G.998.4
compliance of their VDSL2 equipment and chipsets, find and analyze problems
related to G.INP prior to their field deployment, and troubleshoot such
problems on live networks in the field.

"The growth in triple-play service delivery is accelerating VDSL2
deployment, and the VDSL2 lines must be capable of providing adequate
service stability in the presence of impulse noise," said Dr. Hanan
Herzberg, TraceSpan founder and CEO. "The G.998.4 standard is intended to
assure this, but as every new standard it is also introduces new infancy
problems. VDSL Xpert(TM) can now help our customers troubleshoot these
problems quickly and easily using automated or manual testing, thus
minimizing downtime and assuring service reliability and customer
satisfaction."

With its unique multi-layer probing capability, VDSL Xpert(TM) provides
comprehensive analysis with various outputs - from analog samples to bits
and messages. In addition, it extracts the upper layers cells and packets
and provides data, signaling and warnings of incompatibility with the
various protocols. The supported protocols range from PTM, through network
layer protocols such as IP and IGMP, and up to application layer protocols
such as HTTP, as well as TR-069. VDSL Xpert(TM) simultaneously presents
downstream and upstream data and the connection between the two. Its
feature-rich GUI presents multi-layer information in convenient displays,
and also allows automatic generation of exportable reports.

VDSL Xpert(TM) is available in both portable and lab versions, making it
the ideal testing solution for telecom operators' tier-3 customer support
groups and DSLAM and CPE manufacturers' field and development engineers, as
well as lab testing engineers.

The VDSL Xpert(TM) G.INP is a new software module which must be
purchased separately. As a limited-time introduction campaign special terms
for its purchase are given to all of TraceSpan's customers who have a
maintenance contract for their VDSL Xpert(TM) systems and to those who will
renew it by the end of Q3/2011.
